SPLIT GEAR-WHEEL.

SPECIFICATION forming part of Letters Patent N 0. @69,21 1, dated. March 5, 1901.

Application led December 10. 1900. Serial No. 39,256. (No model.)

To LZZ whom, t nea/y concern:

Be it known that we, JOHN CARLSON and BENNET J. MALMFELT, citizens of the United States, and residents of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Split Gear-Wheels,of which the following is a speciiication.

This invention relates to asplit gear-Wheel having a removable rim and which is so constructed that the sections are reliably connected, that the rim is positively supported without being weakened, and that the parts may be readily assembled and separated.

In the accompanying drawings, Figure lis a face View of our improved gear-wheel; Fig.

2, a section on line 2 2, Fig. l; and Fig. 3, a-

section on line 3 3, Fig. l.

The hub is composed of two equal sections adapted to be bolted to each other and also to the rim. Each hub-section a is provided with preferably two spokes CL', having forked ends CL2, Fig. 3. At the. edge of the hub is formed, furthermore, a perforated lug a3 and diametrically opposite thereto an arm a4, having notched end L5 and lying in a plane at right angles to the spokes a. Each toothed rimsectiou b is provided with an inwardly-projecting web b', a lug b2 at one edge, and a lug b3 set back from the other ed'ge a distance equal to the width of the arm CL4.

To connect the parts, the forked ends a2`of spokes CL' are caused to straddle the web b' of rim b, to which they are connected by bolts c. The forked ends CL5 of arms a4 straddle the web b between the lugs b2 baand are connected to the lugs by a pairof bolts d, one at each side of the wheel, Fig. 2. The inner ends of the arms CL4 are connected to the lugs ofV by a pair of bolts e, also one at each side of the wheel. K

It will be seen that in our improved gear- Wheel all the parts may be readily assembled and that great strength, particularly at the connections, is obtained.

What We claim is- 1. A split gear-wheel composed of hub-seo tions having forked spokes, a diametricallyarranged lug and arm, combined with rimsections having a web and lugs, and with bolts for connecting the arms at both ends to adjoining lugs, and the spokes at their outer ends to the web, substantially as specified.

2. Asplit gear-wheel composed of hub-sections having forked spokes, a lug and a forked arm lying in a plane at right angles to the spokes, combined with rim-sections having a web, a lug at one of the edges, and a lug set back from the other edge, and with bolts for connecting the spokes to the web and the arms to the lugs, substantially as specified.

Signed by ns at Brooklyn, county of Kings, and State of New York, this 7th day of December, 1900.
